Troubleshooting filament slip on MakerBot 5

By | December 20, 2016

I run a high school 3D printer lab and we have several 5th generation MakerBot printers. On one of them I have considerable trouble with "thin" prints and filament slip warnings.

So far I've tried changing extruders and using different filament rolls with no luck. But, if I move the job and the extruder to a different printer it works.

I'd appreciate suggestions for how to sort this out. I would have expected the slipping problems to follow the extruder.
